Product Description

The DRN3.1 is an interface that allows microprocessor control of a variable resistance. The DRN3.1’s isolated resistor network can be controlled by several different DDC signal types. It directly replaces a variable resistance controller and simulates the action of a slide wire or rotary potentiometer. All connections of the simulated potentiometer, the wiper and both ends of the resistance range, are available on the DRN3.1terminal strip. The DRN3.1 has on-board failback relays that lock out the original resistive controller during DRN3.1 operation. However, if the DRN3.1 supply power is lost, control of the circuit will revert back to the original controller or user installed shunt, switch, or fixed resistor. This feature allows for remote hand and system override. There are LED indicators for the power and input signals. The DRN3.1 accepts an ANALOG, PULSE, or FLOATING POINT input signal (including triac) and converts it into a proportional resistive output. The output resistance does not wrap around if the input signal exceeds the highest or lowest selected input value. Custom pulse ranges and rates of change, along with custom resistive ranges are available upon request. ANALOG The DRN3.1 accepts an analog voltage or current input and converts higher signals to a higher output resistance. PULSE Jumper shunts allow selection of 3 ranges of pulse width modulated inputs. FLOATING POINT The DRN3.1 increases or decreases the resistive output from digital up and down inputs, at a rate selectable by jumper shunts
